Earnings (Loss) Per Common Unit

Schedule of earnings (loss) per common unit

The following table shows the computation of basic and diluted net income (loss) per common unit for the three months ended March 31, 2013 and 2012, and the weighted-average units used to compute basic and diluted net income (loss) per common unit (in thousands, except per unit data):

	Three months ended March 31,
	2013			2012
Net (loss) income attributable to the Partnership’s unitholders	$	(15,460	)	$	16,020
Less: Income allocable to phantom units	546			520
(Loss) Income available for common unitholders - basic	(16,006		)	15,500
Add: Income allocable to phantom units and DER expense	—			535
(Loss) Income available for common unitholders - diluted	$	(16,006	)	$	16,035
Weighted average common units outstanding - basic	128,615			96,840
Potential common units (Class B and phantom units) (2)	—			20,753
Weighted average common units outstanding - diluted	128,615			117,593
Net (loss) income attributable to the Partnership’s common unitholders per common unit (1)
Basic	$	(0.12	)	$	0.16
Diluted	$	(0.12	)	$	0.14

(1) Earnings per Class B units equals zero as Class B unitholders are not entitled to receive distributions and therefore no income is allocable to Class B units under the two class method.

(2) For the three months ended March 31, 2013, 20,664 units were excluded from the calculation of potential common units because the impact was anti-dilutive.
